Dishwasher Installation FAQs, answered by experts

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.

Regular use helps keep interior dishwasher parts functioning properly and the interior clean. Try to run your machine at least once every two weeks as part of your dishwasher cleaning schedule.

Every six months, running two cups of white vinegar through your dishwasher (place the vinegar where you put detergent) will help deep clean the unit to boost performance.

You should deep-clean your dishwasher every month for optimal performance. A simple scrub down using a homemade vinegar liquid solution is all you need, but don’t use cleaners that aren’t for dishwashers.

If your dishwasher needs repair, expect to spend between $50 and $100 or $100 to $200 per hour to hire a dishwasher repair technician to service your machine.

Treat hard water with water treatment tablets to keep your dishes from getting spotty in between washes. Drop one of these into your dishwasher monthly and run a basic cycle with the machine empty.

A standard dishwasher size is 24-by-24-by-35-inch for a built-in unit. The depth and height line up perfectly with most kitchen countertops and cabinet sizes.

The drain pump will naturally make a standard operational and draining sound several times throughout your dishwasher cycle. If you hear abnormally loud sounds like scraping, grinding, or clicking, you may have food debris or a piece of glass stuck in your drain filter. Avoid dishwasher repair by always scraping food off your dishes and loading the racks correctly.
